1) Abstract away assumptions about all LLVM types being prefixed by 'Int'.
2) Thread through the ability to create a "word" sized type. This is
blocked by a couple bugs.
3) Fix a bug where Int8/UInt8 did not conform to ArrayBounds.
(This bug dates back to when FixedPoint.swift was hand maintained.)

This change is as minimal as possible, which means leaving obsolete
functionality in place (e.g. StringByteData) and even keeping the
"NewString" name in many places. The obsolete functionality was useful
for testing my changes, but expect immediate cleanup commits
addressing all those issues to follow.
* All String bridging now happens in pure Swift code.
* Because String no longer owns an array of UInt8, some assumptions and
assertions are no longer valid. As a result, some code was deleted
and all the code that produces null-terminated strings had to be
rewritten
* test/Constraints/construction.swift had to have one test commented out
because it relied on an element of the String interface that I did not
port forward. It seems to me that this test should declare its own
types and not rely on the stdlib, if it's still valid.
* One test in /test/stdlib/Algorithm.swift had to be disabled pending
<rdar://problem/15736729> and <rdar://problem/15733855>
* This change revealed that test/Interpreter/repl.swift is sensitive to
type-alias names; I had to change a "NewString" to "String" there.
This may indicate a bug somewhere?

struct methods. This does not including properties and subscripts,
but covers the bulk of the change. The implication of this is that
the compiler now rejects mutations of self in a non-@mutating method,
and rejects attempts to call a @mutating method from a non-@mutating
method.
Along with this:
- Fix a refcounting bug in SILGenExpr where I emitted multiple releases
in the rvalue member_ref_expr case, which was exposed by the
testsuite now that rvalues are being used a lot more.
- Change a few native binding things in objc/Foundation to understand
that String is passed by value now when calling size() and that
you can't take the address of self in a non-mutating method (this
should probably pass the components by value instead of passing
&self, for better performance). I filed rdar://15726720 to track
this.
- Update a ton of testcases. We now don't materialize nearly as much
as we used to.
- Brutalize the test/stdlib/Getopt.swift testcase to work, now that
the "GetoptLongOptions().noArgument("foo")" builder pattern doesn't
work anymore (noArgument is a @mutating method, which isn't allowed
on an rvalue temporary).

If there's no script-mode file in a module, don't produce a top_level_code SILFunction for it, and don't consider emitting an LLVM global_ctor for it. We should never emit static constructors from user code anymore.

Along the way created bridging utilities for ObjectiveC functions that
take "out" arguments and added an fmap for operating on Optionals

Collect the bitwise logical operators under a protocol. Add an 'allZeros' static method to produce the 'zero' identity value for the type when used with bitwise operations.

The hack to get the LLVM build system to do what we want is to define a
custom build rule for "XYZ.o" and then add "XYZ" as a dummy source file
to the SOURCES variable, which the LLVM Makefile system uses. To make it
clear that something unusual is going on here, I've changed all existing
instances of this to use "XYZ.o" in SOURCES, rather than having that name
be derived from "XYZ.swift" or whatever.
The actual Swift source files go in SWIFT_SOURCES for the time being
(and possibly forever, since Swift sources will always be built together).

Since our build system isn't really set up to cope with
multi-sourcefile-modules, dump all Foundation support directly into
Foundation.swift

Because we're using a "brute-force" combination of conversion to
NSString and forwarding, this code will continue to work when String
is replaced by NewString. It may not be fast yet, but at least it
will flesh out the experience for Cocoa programmers
Swift SVN r11034
Long ago we decided to eliminate the use of this syntax for type
coercion, but we didn't have a good replacement (now we do: x as T)
and the type checker used this ability to handle string
interpolation. Switch string interpolation over to disjunction
constraints.
